I noticed this back in the 1980's that guys in engineering (Penn State U) who were dealing with low social skills already and a high male:female ratio on campus tended to hit on and beta-orbit plain girls. My friend and I went out to a bar and saw a half dozen guys almost literally orbiting a Rosie O'Donnell lookalike. We got depressed, finished up our brews, and got out of there.The Silky Sasquatch noted during his last livestream that some of the women doing this kind of stuff are quite plain but I believe that taps into something the forum has discussed before, that a lot of men have so little self confidence that a highly attractive woman could not successfully sell these omega males a believable fantasy relationship.
The 5's and 6's (managing their filters to become 6's and 7's) are going to get a lot more attention on these platforms than most people might expect because the reality is that this kind of faux-relationship they're selling has to be at least plausible in terms of what such an omega male might believe he was capable of attaining in real life if it weren't for the various factors real and imaginary they credit for their lack of companionship.
Sort of funny thing happened with our friendship circle. One guy literally married the first girl he laid. She was spoiled (but from a rich family) and plain looking even with beer goggles on. He's happily married to her 32 years later.
The other guy who was pretty red pilled nonetheless found a decent looking, albeit rather harsh,outright feminist willing to have sex with him. I WARNED the guy to not have sex with her and didn't hear from him for 4 months. I called him and said: "I won't say I told you so.." and he said "thanks." We laughed. He had a lovely daughter with her, never married, and then broke up with her about 10 years later. She moved back in with her father in a nice house in New Hope, PA.
I decided, this is back in the 80's now, that if I couldn't have a decent looking (by my standards) woman, who treated me with basic respect, then it just wasn't worth it. I didn't get married until 12 years later.
